Is economical than circular section
Provides self cleansing velocity at low discharges
Is more stable than circular section
Is easy to construct
Answer is Wrong!
Answer is Right!
The correct answer is: B. Provides self cleansing velocity at low discharges.
An egg-shaped section of sewer provides self-cleansing velocity at low discharges because the curved surface of the egg shape helps to keep the water moving in a circular motion. This circular motion helps to prevent sediment from settling on the bottom of the sewer and clogging it.
The other options are incorrect because:
- A. An egg-shaped section of sewer is not necessarily more economical than a circular section. The cost of construction will depend on the specific materials and methods used.
- C. An egg-shaped section of sewer is not necessarily more stable than a circular section. The stability of a sewer will depend on the specific materials and methods used, as well as the soil conditions.
- D. An egg-shaped section of sewer is not necessarily easier to construct than a circular section. The ease of construction will depend on the specific materials and methods used.
